Add oil! 加油

“加油” is a Chinese expression. Originally this meaning came from the gas station, so it means “add more gas into your car” to refill and to continue your smooth drive.
The expression 加 = Add, 油 = Oil is nowadays used to encourage, motivate, cheer people up during occasions or sports events to have a better performance.
Following quotes are my favorite “Add oil”s for life, I would like to share with you. What is your favorite one?
